Locally milder winters, as part of global climate change, may be allowing expansion of afflicted territory. A study conducted in Massachusetts documented that winter moth defoliation reduced the annual trunk diameter growth rate of oak trees by an average of 47% while not significantly impacting growth rates of the less defoliated maple trees.
The larvae roll the leaves of their host, reducing the aesthetic appeal of ornamental canna. Leaf feeding by later instar larvae may be so severe that plants do not flower. In food crops such as arrowroot, severely defoliated plants may produce little of the harvestable rhizome. Adults feed on Lantana in Arizona.
The plant should never be completely defoliated. Propagation is achieved by sowing seeds and from stem cuttings. Seedlings will reach six inches in 3–4 weeks and should be harvested at this time to let them branch out. Stem cuttings will gain roots after they have a week of being soaked in water.
The caterpillars live communally. They come out of hiding in the evening when they swarm the tree trunk and the branches to get to the leaves, which they eat. The caterpillars feed communally until the tree becomes defoliated. At this point they will start searching for a new host, sometimes invading buildings in their search.
Most damage was constrained to downed trees, signs, and power poles. Two trailers were overturned, however, and an oil barge sank in the Key West Harbor.

The fruits of the Spindle Palm are the smallest in the genus (1.2–1.9cm) and they darken to black when ripe. Spindle palms are fairly cold intolerant. They are defoliated at 32 °F (0 °C) and may be killed at anything below that. If the palm does survive a freeze, the next few emerging leaves are stunted.
Palmerton is currently the location of the Palmerton Zinc Superfund site. It was added to the National Priority List in 1983. The site is broken down into four Operable Units: the defoliated slope of Blue Mountain, the cinder banks, the soil in town, and the ground and surface water. The remediation process in Palmerton has been contentious.
The winds uprooted and snapped palm trees across the island and, in some instances, stripped the bark of tree trunks and branches as if they had been sandblasted. Vegetation was completely defoliated across central areas of the island. In some places, it was described as the aftermath of a forest fire. The winds also blew debris across the island.
Based on current knowledge of extant uraniine species, it is likely that Sloane's urania migrated between patches of host plants, after population explosions locally defoliated them. This probably required relatively large, intact areas of lowland forest.(2004) Urania sloanus in The Titian Peale Butterfly and Moth Collection of The Academy of Natural Sciences. Retrieved October 6, 2007.
Logging has been done on the ridge in the early 2000s and plans have been made to construct communication towers on the ridge. Local produce is sometimes traded over Nescopeck Mountain. The mountain is almost completely undeveloped. A gypsy moth infestation began on Nescopeck Mountain in the summer of 2014, causing hundreds of trees to be defoliated.
Trees across Vava'u were completely defoliated, although only 6.6% were killed, leaving no food for the bats. The greatest decline in bats was on Utula'aina Island at 95.7%; A'a Island sustained a complete loss of food-bearing plants. Six months after the storm, the bat population in Vava'u was still only 20% of the pre-storm level.
Trees in the region were completely defoliated. Around 7:50 a.m. a powerful storm surge swept through the city, with flood waters reaching a depth of at Morgerman's location. The fast-rising nature of the water incited panic, residents sheltering at the hotel scrambled to the building's second floor and some broke windows to escape their rooms.
Throughout the city, trees were snapped and defoliated, signs were torn from the ground and tossed around and numerous buildings were damaged or destroyed. Airborne debris shattered windows in a large number of structures. In addition to the tornado, intense lightning was observed, many of which struck buildings, igniting fires. Two buildings were destroyed in the fires caused by the storm.
They mine the leaves of their host plant. Very small young plants can be completely defoliated. The mine is at first slender and serpentine. As the larva becomes nearly full grown, it eats out the whole parenchyma of the leaf and sometimes eats down through the petiole of the leaf to the stem, and sometimes also migrates to another leaf.
Recovery of native riparian grasses can be quite rapid under the once-closed canopy of repeatedly defoliated tamarisk. However, beetle defoliation can locally reduce nesting habitat for riparian woodland birds until the native woodland flora is able to return. In some areas, tamarisk may be replaced by grasslands or shrublands, resulting in losses of riparian forest habitats for birds.(Tracy and DeLoach 1999).
First bamboo shoots are collected from the bamboo forest, then defoliated and boiled in water. Then boiling water is mixed with the shrimp paste. Some chili, garlic paste, salt, and flour are added to the shrimp paste mixed with water. The mixture is heated and, after a few minutes, put on the boiled bamboo shoots on the mixture while still heating.
As a tropical low, Erica brought strong winds to northern Queensland. Several large trees were uprooted, one of which fell on a car in Cape Tribulation and another on a house in Port Douglas. Numerous trees were defoliated and some boats were reported to have been pulling their moorings due to the wind. Power lines were also damaged by the low.
The disease reaches its climax when the crop begins flowering. The cycle of the pathogen continues until the crop is defoliated or until the environment becomes unfavorable to the pathogen. 800x800px The Asian soybean rust is a polycyclic disease: within the disease cycle, the asexual urediniospores keep infecting the same plant. Teliospores (sexual spores) are the survival spores that overwinter in the soil.
Gypsy moth bodily fluid is lethal and swallowtail caterpillars were prone to higher rates of parasitism when placed in the field near gypsy moth infestations. Lymantria dispar dispar causes widespread defoliation and costs the economy millions of dollars in damages. Total defoliation in America, from 1970 to 2010, was .Defoliation chart from US Forest Service The worst year was 1981 with defoliated.
Schorn and Wehr placed the different detached organ fossils in the same species based on a number of factors. Where visible, all the cone scales have bracts and are morphologically similar. The scales display impressions on the admedial surface of wing seeds that match the fossil seed dimensions. The needle arrangement is consistent on both foliated and defoliated axes, with attached needles matching isolated needles.
In 1981, 12.9 million acres (52,200 km2) were defoliated. In wooded suburban areas, during periods of infestation, gypsy moth larvae crawl over man-made obstacles and sometimes enter homes. When feeding, they leave behind a mixture of small pieces of leaves and frass, or excrement. During outbreaks, the sound of moths chewing and dropping frass may be loud enough to sound like light to moderate rainfall.
After nuclear war has defoliated the Earth, the survivors live in colonies in a endless quest for drinkable water. A young woman named Delha is on the run from the evil warlord Kardis and his henchman. She is rescued by Stryker and his young companion Bandit. She later finds herself trapped again by Kardis and resists torture to reveal the location of her colony.
"Historians are unsure as to how Galloway got its name. One opinion is that it was named after an area in Scotland known as Galloway Mull. The other theory is that it was named after Joseph Galloway, a Loyalist delegate to the Continental Congress." During the spring of 2007, a large swath of oak and other hardwood trees were defoliated by the Gypsy moth caterpillar.

Australian gunners on a alt=Soldiers walk across duckboards amidst a defoliated forest In March 1917, the 2nd and 5th Divisions pursued the Germans back to the Hindenburg Line, capturing the town of Bapaume.
In November 1969, COMUSMACV General Creighton Abrams endorsed Zumwalt's first-priority effort to establish a permanent South Vietnamese government presence in Ca Mau, in Operation Solid Anchor. Additional resources poured in. U.S. Air Force planes defoliated the terrain surrounding both Năm Căn and Sea Float with Agent Orange to deny the VC cover and concealment. South Vietnamese ground troops reinforced the area's defense forces.
Winds also defoliated shrubbery and downed trees and signs. Trees and electrical poles were downed as far north as Fort Lauderdale, leaving some power outages. Some citrus and pineapple crops were damaged throughout South Florida, while low- lying vegetables were ruined considerably due to flooding. Offshore Florida, three sailing vessels were wrecked in the storm - the British Melrose, the German Zion, and the American James Judge.
By 1987, the gypsy moth had established itself throughout the northeast US, southern Quebec, and Ontario. The insect has now spread into Michigan, Minnesota, Virginia, West Virginia, Illinois, and Wisconsin. Small, isolated infestations have sporadically occurred in Utah, Oregon, Washington, California, and British Columbia, but efforts have been taken to eradicate them. Since 1980, the gypsy moth has defoliated over one million acres (4,000 km2) of forest each year.
Six people were killed after the motor boat they were on was picked up by the tornado and thrown across the Baitarani River. Survivors of the storm said that the destruction matched that of the 1999 Orissa cyclone. Trees throughout the area were defoliated and debris littered the ground and hung from trees. The day following the tornado, high temperatures were present, but residents struggled to find shelter from the heat.
Older larvae eat the whole needle before moving on to the next. The larvae are gregarious, and can strip whole branches and trees of needles. If the tree is completely defoliated, the larvae move as a group onto a neighboring tree, or may start chewing at the soft bark of twigs. When their development is finished, they drop to the ground and spin cocoons in the needle litter or underground.
Mating starts late in the day and copulations are short. In contrast, during high-density outbreaks, mating takes place on lower vegetation, presumably because caterpillars descend to forage in less defoliated areas, where they form their pupae. This high population density increases the operational sex ratio and significantly intensifies male-male competition. As a result, copulations begin earlier in the day and last longer in an attempt to minimize sperm competition.
The American sycamore is a favored food plant of the pest sycamore leaf beetle. American sycamore is susceptible to plane anthracnose disease (Apiognomonia veneta, syn. Gnomonia platani), an introduced fungus found naturally on the Oriental plane P. orientalis, which has evolved considerable resistance to the disease. Although rarely killed or even seriously harmed, American sycamore is commonly partially defoliated by the disease, rendering it unsightly as a specimen tree.
On hatching, the first instar larvae feed on growing shoot tips and may kill them. Later instars feed on stems and leaves leaving the upper cuticle of the leaf intact. When the density of the larvae is high enough, the plant can be completely defoliated. After feeding for about three weeks and undergoing further moults, the larvae move down the plant to pupate in the soil or leaf litter.
The Invid are a fictional alien race in the Robotech storyline. They appear in the New Generation portion of the series. Invid are invertebrate, bipedal, crab-like creatures that came from a now uninhabitable planet. Their world was defoliated by the Robotech Masters in an attempt to monopolize the Flower of Life, a powerful narcotic that was native to the planet and also the source of an incredibly powerful energy source.
The pine sawfly Diprion pini is a serious pest of forestry. Caterpillar-like larvae of Iris sawfly on yellow flag, showing damage to host plant Sawflies are major economic pests of forestry. For example, species in the Diprionidae, such as the pine sawflies, Diprion pini and Neodiprion sertifer, cause serious damage to pines in regions such as Scandinavia. D. pini larvae defoliated in the largest outbreak in Finland, between 1998 and 2001.
An additional fatality occurred during evacuations in Jalisco. In Emiliano Zapata and Chamela, the villages most badly affected by Patricia, violent winds tore off roofs, toppled concrete power poles and transmission lines, and defoliated trees. Hillsides were left barren and most small structures were severely damaged or completely destroyed. Mexico's agricultural sector also suffered, with 42,000 ha (100,000 ac) of crops affected by Patricia, of which 15,000 ha (37,000 ac) were deemed a total loss.
Although damage to mangroves was minor, the cyclone defoliated swaths of many coastal and island forests. For the most part, cays and reefs were unharmed, with no visible change in the general appearance or shape of reefs and little underwater change as well. It was noted, however, that water clarity surrounding certain reefs was poor. River plumes of the Herbert, Tully, Murray, Hull, Johnstone, and Mulgrave/Russell rivers were noticeably changed, with some paths diverted.
Three varieties are recognised and it hybridises with the silver and dwarf birches. A number of cultivars have been developed but many are no longer in cultivation. The larva of the autumnal moth (Epirrita autumnata) feeds on the foliage and in some years, large areas of birch forest can be defoliated by this insect. Many fungi are associated with the tree and certain pathogenic fungi are the causal agents of birch dieback disease.
In Amelia, a suburb of Beaumont, officials helped residents in low-lying neighborhoods to higher ground, and in Beaumont proper, flooding inundated streets, rendering some impassible. The hurricane partially defoliated palm trees, leaving palm fronds on streets and roadways, and several structures were toppled or damaged along the coast. Overall damage, however, was minimal. An levee sheltering Port Acres ruptured, forcing residents to stack 11,000 sandbags and dump sand to protect the suburb.
The bird appeared to have always had a small population. When people brought cattle and created ranches in the koa forests, the younger koa trees began to be trampled by the cows. The cows also stripped the leaves off the trees at a faster rate than the leaves normally fell. The older trees were too tall to be defoliated, but their roots were kicked and pulled out, causing them to grow weak and eventually die.
In part 3, Thomas goes to Washington, D.C. with Dwight and some other men to visit the Vietnam Veterans Memorial. At the memorial, Thomas solemnly reflects on his life in Vietnam. He is reminded of the barren landscapes bombed and defoliated, and the hostility of his unit. He sees his own name on the wall with a circled cross next to it, and suddenly begins to cry as he thinks about the people in his troop that he killed.
The ground was "literally covered" with fruit, including guava, lemons, and lime, while pineapple fields were flattened. Power and telegraph lines and trees, including many large pine trees, were toppled throughout the city. Offshore, a Standard Oil barge was beached against a reef; the crew of eleven men were forced to swim ashore. The settlements of Pompano, where the eye was believed to have come ashore, and Delray Beach were nearly destroyed, with trees defoliated and many buildings dismantled.
When trees are defoliated two or more years in a row, this leads to "branch dieback, loss of diameter growth, and tree decline". The oak leaftier has caused "considerable tree mortality", especially in the Appalachian region. Dead wood in affected trees is attacked by fungi such as the shoestring root fungus and wood borers like the twolined chestnut borer. A major outbreak occurred in the 1960s and 1970s in Connecticut, Massachusetts, New York, Pennsylvania, Virginia, and West Virginia.
The leaves are 5–10 cm in length and often drop in late summer due to defoliation by leaf diseases. The tree seems to suffer little from the early loss of its leaves. Among the earliest in the genus to bloom, downy hawthorn also has earliest ripening fruit, which decorate the defoliated tree in late summer and early fall. The large brightly colored edible fruit of the species ripen from the middle of August to early in September.
Mangroves in the continental United States are found mainly in the Florida peninsula (see Florida mangroves), Louisiana and South Texas, as well as other isolated areas along the wider Gulf Coast. They can be found, at their northernmost extent, at the Georgia coast. The trimming of mangroves in Florida is regulated, and altering a mangrove without a permit (removing or cutting the plant so much that it dies or is defoliated) is prohibited and carries a fine.
As the storm moved over Étrochey, the tornado destroyed a stone barn, debarked and defoliated trees, broke concrete electrical poles, and tossed a heavy gate several hundred meters. Tiles from the roofs of damaged buildings were found up to away embedded in the ground. As it moved into Montliot-et-Courcelles, a home was largely destroyed, with debris strewn over several hundred meters. Overall, the tornado moved along a discontinuous path long and reached a maximum width of .
A third of cotton, much of which defoliated, was lost to the rain. However, these losses were offset by the increased soybean yield resulting from the same rainfall. A number of pecan tree limbs were torn down, though relative to the overall pecan production for the state these losses were negligible. The rains also caused both the Black and White Rivers in the eastern part of the state to rise from to ; however, they did not exceed flood stage.
Approximately $2.4 million worth of agricultural plantations and structures constructed using recovery funds from the 1928 hurricane were destroyed. Forests along the Sierra de Luquillo were defoliated and exhibited high tree mortality after being lashed by the heavy rains and strong winds. East of the Puerto Rican mainland, Culebra and Vieques also sustained heavy damage. Workers from the Puerto Rican Department of the Interior, assisted by prisoners and volunteers, quickly cleared roads of debris once the storm passed.
Mangroves in the Delta region required only one spraying and did not survive once defoliated, whereas dense forests in the uplands required two or more spray runs. Within two to three weeks of spraying, the leaves would drop from the trees, which would remain bare until the next rainy season. In order to defoliate the lower stories of forest cover, one or more follow-up spray runs were needed. About 10 percent of the trees sprayed died from a single spray run.
This species is distributed from southern México, to Venezuela and Ecuador. It has been found growing from sealevel to , in temperatures ranging from 20 °C to 30 °C on average, with annual rainfall above 500 mm, and on soils with very variable pH. This tree is often seen in Neotropical cities, where it is often planted in parks and gardens. In the rainy season it offers shade and, in the dry season, abundant flowers are present on the defoliated trees.
Olive peacock spot disease is a worldwide agricultural problem and it thrives in similar conditions wherever it occurs. It depends on mild to low temperatures and free moisture to germinate and so it usually infects in the fall, winter, and spring. Hot and dry conditions in the summer cause the fungus to become inactivated and the leaf spots to turn white and crusted. During the summer, the diseased leaves fall leaving only the healthy ones on the partially defoliated trees.
Debris obstructed roads across northern Queensland and power outages disrupted electrical service, even at water treatment plants, forcing officials to warn residents to boil water as a precautionary measure. Overall, the cyclone caused $86.4 million in agriculture-related damages, with sugar cane and banana harvests suffering the most. Tourist operations were generally uninterrupted by the storm, while ecological and environmental damage, if any, was mild. Even so, high winds uprooted trees in wide swaths of forests, with those not completely defoliated.
The insect then appeared to be dormant in US forests until 1922, when two outbreaks were reported near Priest Lake in northern Idaho. Since then, significant outbreaks in the Rockies and in the Pacific Northwest have caused top-killing and serious economic losses in tree growth. Tree mortality from budworm can occur in regeneration, sapling, and pole-sized trees. Trees in mature stands severely defoliated by the western spruce budworm may become susceptible to bark beetles, which kill mature trees.
The caterpillars feed mostly on acacia (wattle) trees and Grevillea striata (beefwood). If they have totally defoliated their food tree, the caterpillars migrate to seek out another one, leaving a silk trail. When a caterpillar of the species encounters such a trail it will follow it, especially if there is a pheromone scent associated with it. There can be a hundred or more caterpillars in a head-to-tail procession, kept together by contacting the tail hairs of the caterpillar in front.
For instance, it led to 3 million Vietnamese people suffering health problems, one million birth defects caused directly by exposure to Agent Orange, and 24% of the area of Vietnam being defoliated. Additionally, the toll on the United States military handling the above- mentioned chemicals, as well as those who happened to be in and around the many targeted drop zone areas throughout the Viet Nam War, adds 2.8 million personnel and their offspring exposed to, and suffering the effects of, the various chemicals used.
Mangrove forests, like the top one east of Saigon, were often destroyed by herbicides. About 17.8%——of the total forested area of Vietnam was sprayed during the war, which disrupted the ecological equilibrium. The persistent nature of dioxins, erosion caused by loss of tree cover, and loss of seedling forest stock meant that reforestation was difficult (or impossible) in many areas. Many defoliated forest areas were quickly invaded by aggressive pioneer species (such as bamboo and cogon grass), making forest regeneration difficult and unlikely.
Although the biological control program dramatically decreased the population of the moth, it is still possible that it exists today, but in very small numbers. The levuana moth preferentially attacks the tallest coconut palms in highly localized areas. When the tallest palms are defoliated, the moth moves on to shorter ones. Based on the fact that severe outbreaks no longer appear, it is theorized that this insect solely inhabits its preferred feeding sites: the tallest trees, in small quantity, leading to visual searches on small immature coconut palms to be unsuccessful.
Unlike expensive chemical and mechanical controls of tamarisk that often must be repeated, tamarisk biological control does not harm native flora and is self-sustaining in the environment. Recovery of native riparian grasses can be quite rapid under the once closed canopy of repeatedly defoliated tamarisk. However, tamarisk beetle defoliation can locally reduce nesting habitat for riparian woodland birds until native woodland flora are able to return. In some areas, tamarisk may be replaced by grasslands or shrublands, resulting in losses of riparian forest habitats for birds (Tracy and DeLoach 1999).
Up to 75% of the trees may die after such outbreaks, as D. pini can remove all the leaves late in the growing season, leaving the trees too weak to survive the winter. Little damage to trees only occurs when the tree is large or when there is minimal presence of larvae. Eucalyptus trees can regenerate quickly from damage inflicted by the larvae; however, they can be substantially damaged from outbreaks, especially if they are young. The trees can be defoliated completely and may cause "dieback", stunting or even death.
A tree stripped by gypsy moth larvae Aerial photo showing gypsy moth defoliation of hardwood trees along the Allegheny Front near Snow Shoe, Pennsylvania, in July 2007. The light green patches on hilltops are trees that had begun refoliating by the time this picture was taken. The effects of defoliation depend on the species of tree, amount of foliage removed, the health of the tree, the number of consecutive defoliations, and available soil moisture. If less than half of the crown is defoliated, most hardwood species will experience only a slight reduction in radial growth.
If more than half of the crown is defoliated, most hardwoods will produce a second flush of foliage by midsummer. Healthy trees can usually withstand one or two consecutive major defoliations. Trees weakened by previous defoliation or subjected to other stresses like droughts are frequently killed after a single half-defoliation. Trees use their energy reserves during re-foliation and may become weakened and exhibit symptoms such as the death of twigs and branches in the upper crown and sprouting of old buds on the trunk and larger branches.
Throughout the poem, Ginsberg contrasts images of the Midwest (and, in particular, the Kansan landscape) with snippets of news reports about the war, and links the violence there with the political conservatism of the Heartland, decrying Carrie Nation's work in Wichita, Kansas as beginning "a vortex of hatred that defoliated the Mekong Delta." The poem also uses images focusing on the sensuality and intimacy of the human body to humanize the violence of the war. Such images are found elsewhere in Ginsberg's work. The title reflects Ginsberg's interest in Eastern religions as well.
Releases of tamarisk beetles in southern California, Arizona, and along the Rio Grande in western New Mexico, are currently delayed until concerns can be resolved regarding safety of tamarisk biological control to nesting habitats of the federally endangered southwestern willow flycatcher (Empidonax traillii extimus), which will nest in tamarisk.(see DeLoach et al. 2000, Dudley and DeLoach 2004). The northern tamarisk beetle has defoliated some tamarisk nest trees of the southwestern willow flycatcher on the Virgin River in southern Utah, and actions to protect the flycatcher are under consideration.
Budworm populations are usually regulated naturally by combinations of several natural factors such as insect parasites, vertebrate and invertebrate predators, and adverse weather conditions. During prolonged outbreaks when stands become heavily defoliated, starvation can be an important mortality factor in regulating populations. This species is a favoured food of the Cape May warbler, which is therefore closely associated with its host plant, balsam fir. This bird, and the Tennessee and bay-breasted warblers, which also have a preference for budworm, lay more eggs and are more numerous in years of budworm abundance.
Large trees were defoliated, snapped, and denuded, and vehicles were tossed and severely damaged. The tornado reached high-end EF3 strength as it moved through neighborhoods just to the west of 34th Street, where multiple homes had roofs ripped off and sustained collapse of exterior walls. One two-story home was completely flattened with only a pile of rubble left behind, though overall context was not indicative of a tornado exceeding high-end EF3 intensity. EF3 damage continued just beyond this point as one-story condominium buildings along Lakeside Lane were destroyed.
Little is known of the biology of this species, but like all squid, it is a predator. Prey items are caught by the tentacles, grasped and moved to the mouth with the help of the arms, and then chewed by the horny beak. In Chile, spawning grounds have been identified at depths of between . Fragile egg masses some long containing about 15 embryos have been found among stems of the kelp Lessonia trabeculata, particularly in places where the algae has been heavily defoliated, suggesting that a semi-protected environment with adequate water movement is desirable.
Scarce dagger larva feeding on the moor birch The larva of the autumnal moth (Epirrita autumnata) feeds on the foliage of Betula pubescens and other tree species. In outbreak years, large areas of birch forest can be defoliated by this insect. Damage to the leaf tissue stimulates the tree to produce chemicals that reduce foliage quality, retarding the growth of the larvae and reducing their pupal weights. In Greenland, about seventy species of fungi have been found growing in association with B. pubescens, as parasites or saprobes on living or dead wood.
A large plume of Saharan Desert dust (light brownish pixels) blown across Libya and Egypt northward over the Mediterranean Sea toward the Middle East, on February 2, 2003. The topographic features of the desert region east of the Nile differ from those to the west of the Nile. The Eastern Desert is relatively mountainous. The elevation rises abruptly from the Nile, and a downward-sloping plateau of sand gives way within 100 km to arid, defoliated, rocky hills running north and south between the Sudan border and the Delta.
On those rare occasions when infestations last for three years or more, tree mortality rates can become significant. Multiple outbreaks in Northern Ontario, Canada, in the 1990s resulted in over six consecutive years of aspen defoliation in some areas. One outbreak in upstate New York and Vermont began in 2002, with 650,000 acres (2600 km²) defoliated in New York and 230,000 acres (930 km²) in Vermont by 2005. Forest tent caterpillar outbreaks tend to recur at reasonably regular intervals every decade or so, with the precise interval varying somewhat in time and space.
As a result, Duke Energy deployed over 500 personnel to restore electrical service, while Tideland EMC handled more than 2,000 outages in Pamlico, Hyde and Craven counties. Strong winds toppled trees and power poles in Hyde County and Ocracoke Island, and flooding occurred just south of downtown Wilmington, North Carolina. On other areas along the coast, flood waters reached deep; with widespread coastal erosion observed in many areas. Meanwhile, at Wrightsville Beach, the hurricane tore off shingles and partially defoliated palm trees, and in Manteo, of water inundated several businesses.
The first major outbreak occurred in 1889, and Forbush and Fernald recount the extent of devastation: all the trees being defoliated and caterpillars covering houses and sidewalks and raining down upon residents. At first it was uncertain what species was responsible for the outbreak, but after the caterpillar was identified by entomologist Maria Elizabeth Fernald, an eradication program began in 1890.Spear, Robert J. The Great Gypsy Moth War: The history of the first campaign in Massachusetts to eradicate the gypsy moth, 1890-1901. University of Massachusetts Press, 2005.
The herbicide spraying missions began in Vietnam in 1961, and it has recently been revealed that some took place from Thai bases, including Takhli, as early as 1966. This pre-dates the USAF receiving permission to use herbicides for clearing areas on and around Thai bases for area and perimeter defense, which was given in 1969. The missions in 1966 defoliated areas surrounding parts of the Ho Chi Minh Trail in Laos, near the Vietnam border and north of the Vietnamese Demilitarized Zone and had the approval of both the Thai and Laotian governments. C-123 aircraft were used on the missions.
The larger tamarisk beetle is currently weakly established as a biological control agent for tamarisk in west Texas. Populations of larger tamarisk beetle from around 39°N latitude near Qarshi, Uzbekistan were initially released by the USDA Agricultural Research Service in west Texas in 2006. By 2008, the larger tamarisk beetle had defoliated about 0.2 hectares of tamarisk near Seymour, Texas. The larger tamarisk beetle may be better adapted to warm temperate grassland and desert habitats of west Texas than other Old World tamarisk beetles that are being introduced, such as the Mediterranean tamarisk beetle, Diorhabda elongata.
Ontario, California, 111–154. (PDF) A primary objective of tamarisk biological control with the larger tamarisk beetle is to reduce competition by exotic tamarisk with a variety of native riparian flora, including trees (willows, cottonwoods, and honey mesquite), shrubs (wolfberry, saltbush, and baccharis), and grasses (alkali sacaton, saltgrass, and vinemesquite). Unlike expensive chemical and mechanical controls of tamarisk that often must be repeated, tamarisk biological control does not harm native flora and is self-sustaining in the environment. Recovery of native riparian grasses can be quite rapid under the once closed canopy of repeatedly defoliated tamarisk.
Like most species of Annona, it requires a tropical or subtropical climate with summer temperatures from to , and mean winter temperatures above . It is sensitive to cold and frost, being defoliated below and killed by temperatures of a couple of degrees below freezing. It is only moderately drought-tolerant, requiring at least 700 mm of annual rainfall, and will not produce fruit well during droughts. It will grow from sea level to and does well in hot dry climates, differing in its tolerance of lowland tropics from many of the other fruit bearers in the Annona family.
Overall, the hurricane damaged the roofs of as much as 98% of the island's buildings, including those serving as shelters; half of the houses had their frames destroyed. Its ferocious winds defoliated nearly all vegetation, splintering or uprooting thousands of trees and decimating the island's lush rainforests. The agricultural sector, a vital source of income for the country, was completely wiped out: 100% of banana and tuber plantations was lost, as well as vast amounts of livestock and farm equipment. In Maria's wake, Dominica's population suffered from an island-wide water shortage due to uprooted pipes.
Archips semiferanus (also known as Archips semiferana) is a species of moth in the family Tortricidae, and one of several species of moth commonly known as oak leafroller or oak leaf roller. The larvae feed on the leaves of oak trees in the eastern United States and southeastern Canada and are a major defoliator of oak trees, which can lead to tree mortality. In Pennsylvania in the late 1960s and early 1970s, oak leafrollers defoliated over . Adult Archips semiferanus moths lay masses of 40 to 50 eggs on oak tree branches and rough bark in July; these overwinter and hatch the next spring.
A typhoon watch was issued for Rota, Tinian, and Saipan on December 14, which was upgraded to a typhoon warning the next day. Because Paka was intensifying while passing to the south of Rota, the first wind, or northeast through east winds, was less severe than the second wind from the southeast. Sustained winds on the island reached 145 km/h (90 mph), with gusts reaching 185 km/h (115 mph). Many trees in the mountainous portion of the island were left defoliated, which limited nesting and foraging sites for the endangered bridled white-eye bird.
Old-growth forest is defined as unharvested stands that are older than 80 years of age. The stand-scale habitat use includes mature coniferous forest being the dominant cover types used proportionately more than the availability, along with coniferous scrub and insect-defoliated stands used in proportion to the availability, whereas open areas and fire disturbed area are avoided. However, the fire disturbance is minimized because of the lack of prolonged dry periods on the island. Due to infrequent fires, the episodic defoliation by the spruce budworm and hemlock looper are the primary form of natural stand-replacing disturbance.
Nests are conspicuous, usually in the open and away from surrounding vegetation, attached from an often defoliated limb, bamboo stem or vine, hanging above a clearing or a stream at a height of . The nest is attached to its hold by a long rope. It is shaped like a retort, having an oval nesting chamber high and in diameter and a vertical entrance hose is attached high up a side and is at least as long as the nest is high. It is a firm construction made from strips of grass, sedge, and palm fronds, with a thin lining of palm fibres at the bottom of the nesting chamber.
Several other rural homes were destroyed, and large amounts of gravel was blown off of gravel roads in the area, with only the dirt underneath left at some locations. Several large metal electrical transmission poles were downed, trees were snapped and defoliated, and multiple vehicles were tossed from roadways in the area. At least 29 buildings and 40 vehicles were damaged or destroyed by the tornado, with repairs in the El Reno area expected to take at least a year. On June 1, the American Red Cross set up a shelter at the Redlands Community College in El Reno for victims of the storm.
Exceptionally, trees may be partially defoliated by it, but the damage is rarely this severe. Among Lepidoptera, apart from some that feed on Pseudotsuga in general (see there) the gelechiid moths Chionodes abella and C. periculella as well as the cone scale-eating tortrix moth Cydia illutana have been recorded specifically on P. menziesii. Mature individual in the Wenatchee Mountains The coast Douglas-fir variety is the dominant tree west of the Cascade Mountains in the Pacific Northwest, occurring in nearly all forest types, competes well on most parent materials, aspects, and slopes. Adapted to a moist, mild climate, it grows larger and faster than Rocky Mountain Douglas- fir.
The northern tamarisk beetle is currently the most successful biological control agent for tamarisk in North America. Populations taken from around 44°N latitude at Fukang, China, and Chilik, Kazakhstan, were initially released by the USDA Agricultural Research Service in 2001. Since its release, the insect has defoliated tens of thousands of acres of tamarisk in Nevada, Utah, Colorado, and Wyoming. However, it appears to be poorly adapted to some areas where other species of Old World tamarisk beetles are being introduced, such as the Mediterranean tamarisk beetle, Diorhabda elongata, in northern California and parts of West Texas, and the larger tamarisk beetle, Diorhabda carinata (Faldermann), and the subtropical tamarisk beetle, Diorhabda sublineata (Lucas), in parts of West Texas.
The MTB is currently the most successful biological control agent for tamarisk in west Texas. Populations of MTB from around 35°N latitude near Sfakaki, Crete, Greece were initially released by the USDA Agricultural Research Service in west Texas and northern California in 2003. By 2008, the MTB had defoliated over 140 hectares in Texas and 250 hectares in California. However, the MTB may not be as well adapted to interior desert and grassland habitats of south and west Texas as three other species of Old World tamarisk beetles that are being introduced, the larger tamarisk beetle (Diorhabda carinata), in north Texas, the subtropical tamarisk beetle (Diorhabda sublineata) in south Texas, and the northern tamarisk beetle (Diorhabda carinulata) in extreme northern Texas.
Friendship Oak in December 2005, approximately 3 months after Hurricane Katrina devastated the Mississippi Gulf Coast Numerous weddings have taken place beneath the branches of the Friendship Oak.Weddings Retrieved 2011-10-12 Treehouse Retrieved 2011-10-12 Most of the wedding ceremonies have been celebrated by former students of Gulf Park College or the University of Southern Mississippi. Through the centuries, hurricane winds have defoliated the Friendship Oak and subjected its roots to seawater pushed inland from the Gulf of Mexico as storm surges. At least twice since the mid-1950s, acorns from Friendship Oak have been gathered to produce seedlings for replanting along the Mississippi Gulf Coast to replace live oaks that were destroyed by Hurricanes Camille (1969) and Katrina (2005).
54 The Rose-in-Bloom was caught in the hurricane while offshore of Barnegat Inlet, New Jersey,Hairr 2008, p. 35 en route to New York City from Charleston, but was struck by a large wave which overturned the ship, resulting in the deaths of 21 of its 48 passengers and the loss of $171,000 of its $180,000 (1806 USD) cargo. The vessel only barely stayed afloat, with 30 bales of cotton preventing it from sinking entirely; survivors were ferried to New York by the British brig Swift, which had then been traveling toward St. John's, Newfoundland. The hurricane produced strong gusts within the vicinity of New York City, and at Belleville, New Jersey, several peach trees were defoliated and uprooted.
In Michigan, an EF2 tornado severely damaged two homes and downed numerous trees near the town of Millington. The strongest and most destructive tornado of the outbreak initially touched down after dark as a weak tornado south of Morris, Illinois, causing roof and chimney damage to homes, and downing trees and power poles as it moved along a southeasterly path. The storm intensified and widened rapidly as it entered Coal City, reaching nearly a mile wide in diameter and attaining high-end EF3 strength. Numerous anchor- bolted frame homes in Coal City were damaged or destroyed, and a few were leveled or swept from their foundations (though vehicles parked at these residences were not moved, and nearby vegetation was not defoliated or debarked, precluding a higher rating).
Biological control of tamarisk by the MTB will not eradicate tamarisk but it has the potential to suppress tamarisk populations by 75–85%, after which both MTB and tamarisk populations should reach equilibrium at lower levels (DeLoach and Carruthers 2004, Tracy and DeLoach 1999). A primary objective of tamarisk biological control with the MTB is to reduce competition by exotic tamarisk with a variety of native riparian flora, including trees (willows, cottonwoods, and honey mesquite), shrubs (wolfberry, saltbush, and baccharis), and grasses (alkali sacaton, saltgrass, and vinemesquite). Unlike expensive chemical and mechanical controls of tamarisk that often must be repeated, tamarisk biological control does not harm native flora and is self-sustaining in the environment. Recovery of native riparian grasses can be quite rapid under the once closed canopy of repeatedly defoliated tamarisk.
A violent F4ARPAV: storms of 08/07/2015 on Veneto tornado impacted areas in and around the towns of Pianiga, Dolo and Mira, causing major damage and several casualties within the Riviera del Brenta region of Italy, famous for its villas and channels. About 500 buildings were badly damaged or destroyed, and among them was the large, two-story, masonry construction Villa Fini restaurant and hotel from the 17th century, which was almost entirely leveled to the ground. Many trees were defoliated, snapped, and partially debarked, and numerous cars were tossed and mangled, a few of which were thrown into canals and submerged. As the tornado impacted rural areas, homes and farmsteads were severely damaged or destroyed, metal high-tension truss towers were toppled to the ground, and agricultural fields were scoured.
A published study in the Journal of Agricultural and Food Chemistry reported that through successive surface runoff events in defoliated cotton fields, defoliant concentrations decreased exponentially within the test area and could negatively affect marine life in the runoff zones. Agent Orange, a defoliant used by the United Kingdom during the Malayan Emergency in the 1950s and the United States during the Vietnam War to defoliate regions of Vietnam from 1961 to 1971, has been linked to several long-term health issues. Agent Orange contains a mixture of 2,4-D and 2,4,5-T as well as dioxin contaminants. Members of the Air Force Ranch Hand and the Army Chemical Corps who served in the Vietnam War were occupationally exposed to Agent Orange have a higher incidence of diabetes, heart disease, hypertension, and chronic respiratory diseases.
Handicapped children in Vietnam, most of them victims of Agent Orange, 2004 Although herbicidal warfare use chemical substances, its main purpose is to disrupt agricultural food production and/or to destroy plants which provide cover or concealment to the enemy. During the Malayan Emergency, Britain was the first nation to employ herbicides and defoliants in order to deprive the communist insurgents of cover and targeting food crops as part of the starvation campaign in the early 1950s. The use of herbicides as a chemical weapon by the U.S. military during the Vietnam War has left tangible, long-term impacts upon the Vietnamese people that live in Vietnam. For instance, it led to 3 million Vietnamese people suffering health problems, one million birth defects caused directly by exposure to Agent Orange, and 24% of the area of Vietnam being defoliated.
By August 2010, the STB had defoliated about 23 miles of tamarisk along the Rio Grande near Presidio, but it was causing concern by also defoliating the related but non-target athel tamarisk (Tamarix aphylla) trees, a taller species of tamarisk used around Presidio and neighboring Mexican communities for shade (Haines 2010). The STB may be better adapted to subtropical interior desert habitats and subtropical Mediterranean habitats than other Old World tamarisk beetles that are being introduced, such as the Mediterranean tamarisk beetle, Diorhabda elongata. The northern tamarisk beetle, Diorhabda carinulata, is probably better adapted to northern cold deserts in North America where it is widely established, and the larger tamarisk beetle, Diorhabda carinata, is probably better adapted to warm temperate grasslands and deserts (Tracy and Robbins 2009). Tamarisk does not usually die from a single defoliation from tamarisk beetles, and it can resprout within several weeks of defoliation.
By 2015, 97% of the population had access to improved water sources. In 2016, Vietnam's national life expectancy stood at 80.9 years for women and 71.5 for men, and the infant mortality rate was 17 per 1,000 live births. Despite these improvements, malnutrition is still common in rural provinces. Since the partition, North Vietnam has established a public health system that has reached down to the hamlet level. After the national reunification in 1975, a nationwide health service was established. In the late 1980s, the quality of healthcare declined to some degree as a result of budgetary constraints, a shift of responsibility to the provinces and the introduction of charges. Inadequate funding has also contributed to a shortage of nurses, midwives and hospital beds; in 2000, Vietnam had only 24.7 hospital beds per 10,000 people before declining to 23.7 in 2005 as stated in the annual report of Vietnamese Health Ministry. The controversial use of herbicides as a chemical weapon by the US military during the war left tangible, long-term impacts upon the Vietnamese people that persist in the country today. For instance, it led to three million Vietnamese people suffering health problems, one million birth defects caused directly by exposure to the chemical and 24% of Vietnam's land being defoliated.
